When checkering surfaces such as backstraps, triggerguards, grip frames, ribs, and hammer spurs to improve their grip, one can achieve accurate line spacing only through a particular method. This method involves creating finer cuts on the surface which creates a nice matting effect that reduces glare and light distortion. The process for checkering is similar to that used with wood. Firstly, one should layout the master lines or use a guide like the .45 Checkering Guide, then establish the pattern by moving the file incrementally and in correlation with the previous lines. After creating the pattern, one should bring it to the final depth using a 60° needle file.
